“If you have ever petted a shark in an aquarium touch tank,” said Erin Dillon, who began this study as an intern at the Smithsonian Tropical Research Institute (STRI) and is now wrapping up her doctoral work at the University of California, Santa Barbara, “denticles are the reason why shark skin is rough like sandpaper if you rub it in one direction yet smooth in the other direction. Sharks are essentially covered by millions of tiny teeth.”
Say it with me: Every shark is completely smooth no matter what angle you’re touching it from
No. I don’t think I will.

Nah that must’ve been a weird one, all the sharks I’ve pet have been totally smooth each way
Yeah I’m gonna dip my hands in the ocean and touch some smooth sharks
Nice!
